老师好，这道题我错在求Terminal Value用的是第三年的折现率求PV，而答案给的是用第二年的折现率求PV。仔细读题目后，发现题干里提到求Terminal Value是从第三年开始。我的问题是题目里先说的前3年ROE高于12%，从第四年开始永远保持12%，我理解算Terminal Value应该是从第四年开始计算更合理？感觉题目这种表述前后矛盾了。
谢谢！

1、你的问题第一句话我没看懂，cost of equity保持不变，无论第几年折现，折现率都是8.7%
2、因为协会的公式：PVRIT-1=RIT/(1+R-W),RIT是第三年，那么PVRI求得就是第二年，因此折两年
3、这道题ROE的条件给的不严谨不用纠结，但是最后一句对于未来RI有准确的要求：The terminal value is based on an assumption that residual income per share will be constant from Year 3 into perpetuity.

请问这题如果用李老师的公式是不是应该PVRI3=RI3/Re

是的，但你别忘了这样做还需要将RI3折现。加起来还是33.78.
